Options Strategies: ILMN & AMZN

Here are some sample options strategies on two stocks, which show what happens under various types of options scenarios. The two underlying stocks are ILMN and AMZN. For this exercise, I pulled daily options quotes from CBOE.com http://www.cboe.com/DelayedQuote/QuoteTable.aspx

Before you consider playing with options be sure you know when they expire! Here is the 2012 expirations calendar: http://www.cboe.com/AboutCBOE/xcal2012.pdf

Basics: When you trade options contracts the standard contract size is 100 (options- calls or puts)

Strike price is the price on the face of the option.

Uncovered Option - A type of options contract that is not backed by an offsetting position that would help mitigate risk. “Trading naked”, as it is called, poses significant risks. However, an uncovered options contract can be profitable for the writer if the buyer cannot exercise the option because it is out of the money.

To translate this Jargon: uncovered or naked option is when you don’t own the stock or a commodity but you sold a call or a put contract. You can also be uncovered when you buy a put, which will give you the right to sell a stock or a commodity at a strike price, when it’s higher then the current price of the stock. Buying an uncovered put is not risky because you will almost always be able to buy the security at a lower price and will be able to resell it to the put writer at the strike price.

Out of the money options are those that have a strike price that is too high or too low making them worthless before they expire.

Here is an example of writing uncovered calls and puts:

You can see that because ILMN did not fluctuate before the expiration date the writer of the hypothetical call and the put earned 60 and 28 dollars respectively. Here is how it worked: It would not make sense for the holder of the call to exercise it because the strike price was $50, which is higher then $49.93 (the stock closed before the expiration date). On the other hand, the holder of the put contract could have exercised the put and made the writer buy the stock from them at $50. The assumption is that the writer would turn around and sell it at $49.93, thus losing $7 on 100 shares.



This table also shows the possible loss in the even the underlying stock went up. When it comes to calls the possible loss is really unlimited. On the other hand the loss on puts is limited to the multiple of the difference between the strike prices on the put and the close price of the stock before expiration.



Now in the example with AMZN you’ll see that the stock jumped from $184 to $195 in 12 days. Also, you’ll notice that due to this change the options did not expire on the “expiration calendar date” but continued to trade through the 23rd. The writer of the call ended up loosing $969, because they had to sell the stock to the call holder at $180, while it was trading at $195. But because there was a profit from the original sale of call options was $535 the loss was not the full $1,500. Put expired unexercised because the strike price was lower then the close.



An uncovered bull call spread is constructed by buying a call option with a low exercise price, and selling another call option with a higher exercise price. Often the call with the lower exercise price will be at-the-money while the call with the higher exercise price is out-of-the-money. Both calls must have the same underlying security and expiration month.

This is a strategy will work if the stock is expected to go up beyond the shorted (sold call option strike price). You see that because ILMN did not move very much the investor would have lost $45. They let the call contracts bought for $60 expire and the written call contracts sold for $15 expired unexercised.



An uncovered bull put spread is constructed by selling higher striking in-the-money put options and buying the same number of lower striking in-the-money put options on the same underlying security with the same expiration date. The options trader employing this strategy hopes that the price of the underlying security goes up far enough such that the written put options expire worthless.

As you can see, this strategy worked well in both scenarios but was particularly successful for AMZN because of the drastic change in price. In other words the naked puts written went on unexercised and puts purchased cost less then the gain.



Uncovered Short Call Butterfly



A short butterfly position will make profit if the future volatility is higher than the implied volatility.



1.      Sell 1 ITM Call

2.      Buy 2 ATM Calls

3.      Sell 1 OTM Call

In The Money (ITM):



1.      For a call option, when the option's strike price is below the market price of the underlying asset.

2.      For a put option, when the strike price is above the market price of the underlying asset.

In this situation the combination worked against the investor in both scenarios. Max Profit = Net Premium Received - Commissions Paid. Max Profit is Achieved When Price of Underlying <= Strike Price of Lower Strike Short Call OR Price of Underlying >= Strike Price of Higher Strike Short Call.
